New Energy Vehicle Charging Equipment: Home Charging, Commercial Fast Charging and Connectors

1, Portable home charging gun: flexible emergency, suitable for daily replenishment

Portable charging gun belongs to the AC slow charging equipment, suitable for home 220V power supply. Common product output power of 3.5kW, support for 8A, 10A, 13A and other adjustable current, the average 1 hour can be charged for the vehicle about 3.5 degrees of electricity. Some high-end products support App remote control and timed reservation function.

Steps of use:

1.1 Make sure the three-hole socket has good grounding

1.2 Connect the charging gun plug to the household power supply

1.3 Insert the charging plug into the AC charging port of the vehicle and automatically start charging.

Caution:

a, The socket and power cord used should meet the rated current requirement of the charging gun (usually not less than 16A)

b, Strictly prohibit the use of poor quality extension cords; must use a well-grounded three-hole socket

c, Plugs and sockets should be checked for ablation or looseness before use to ensure safe charging

2, Wall-mounted AC charging pile: high-frequency use of the family's preferred program

Wall-mounted AC charging pile is a fixed installation of slow charging equipment, common specifications for the 7kW (220V, 32A), adapted to the 7-hole plug electric vehicles. It has higher charging efficiency and more stable structure, suitable for repeated daily use.

Installation points:

2.1 The wiring should be completed by a professional electrician, the wire diameter is not less than 3×4mm²

2.2 It must be connected to PE ground wire and equipped with air switch (recommended ≥40A)

2.3 Before installation, report to the local power company to obtain approval for electricity consumption

2.4 If the residence is under centralized management, it is recommended to consult the property management company or owners' committee in advance to ensure the installation complies with the building regulations and safety requirements.

Charging process:

Insert the charging gun → swipe the card or scan the code to authorize → automatically start charging;

Charging will stop automatically after completion to ensure the safety of electricity consumption, and some products support APP remote monitoring.

3. DC Charger: The Best Choice for Efficient Energy Replenishment

DC Charger belongs to fast charging equipment, with a common power range of 30kW to 120kW, and some of the public stations have supported 200kW or even higher output, which is widely used in high-speed service areas, urban fast charging stations and other scenarios.

Technical characteristics:

3.1 The output voltage range is usually 400V-1000V, which can quickly charge the vehicle battery

3.2 Theoretical charging speed is 30-120 kWh per hour, and 80% recharge can be completed in 30 minutes

3.3 The supporting high-voltage fast charging connector needs to meet the requirements of high-current, high-power transmission, with IP67 waterproof, high temperature resistance, high-frequency plugging and unplugging performance.

Operation process:

a. Insert the DC charging gun into the DC charging port of the vehicle

b. Follow the prompts to swipe/scan the code or start the "plug and charge"

c. Press the stop button when finished, and pull out the plug after confirming the power failure.

Suggestions for use:

a. Fast charging should follow the principle of "use when necessary" to avoid long-term reliance on DC fast charging to affect battery life

b. Can not be inserted into the AC and DC interfaces at the same time

c. When the temperature of the environment is too low, the charging power will automatically drop, which is a normal phenomenon.

4. Charging connector technology analysis: the core value of EV Charging Connectors

EV Charging Connectors are a key component for transmitting power and data between EV Charger and vehicles, and its performance directly affects charging efficiency and safety. The current mainstream connectors include the following technical features:

4.1 Real-time monitoring of the plug temperature and automatic power adjustment

4.2 Reduce high-frequency interference and improve system stability

4.3 Meet the needs of 1000V high-voltage platform use

4.4 Plug life design ≥ 10,000 times

4.5 Complete international certifications: such as CE, TÜV, UL, RoHS
